Through Curves option
This command creates a sheet or solid body through a set of up to 150 section strings. A section string can consist of a single object or multiple objects, and each object can be a curve, a solid edge, or a solid face. Through Curves is similar to a Ruled Surface, except that you can specify more than two section strings.
N-Sided Surface option
This option lets you build a surface with an unrestricted number of curves or edges that form a simple, open or closed loop, and assign continuity to outside faces. You can remove holes in surfaces that are not four-sided. Shape control options are available to refine sharpness at center point, while maintaining continuity constraints.
You can use the Section option to construct bodies through sections that you define using conic construction techniques.
You can think of a section free form feature as an infinite family of section curves lying in prescribed planes, starting and ending on, and passing through, certain selected control curves. Additionally, the system obtains conic end slopes directly from the control curves, and uses a continuous 2D conic shape parameter to vary the fullness of the sections along the body.
